Postprandial elevation in plasma bile acids and activation of the bile acid receptor in the liver. (A–C) Fold-changes in plasma levels of cholesterol (A), 7-dehydrocholestrol (B), and taurocholate and taurodeoxycholate (C). (D) qPCR for normalized Nr1h4 (Fxr), Nr0b2 (Shp), Fgf19, and Cyp7a1 mRNA expression in fasted (F), 1, 3, and 10DPF python livers. Data are represented as mean ± SEM. n = 8/group. *, P ≤ 0.05; **, P ≤ 0.01; ***, P ≤ 0.001 versus fasted (F) unless stated otherwise.
